Assume that Todd and Agnes bought x pieces of fruit each.
Yes, see solution.
We are told that Agnes and Todd are making dessert. Agnes buys apples and a jar of honey and Todd buys peaches and a carton of vanilla yogurt. Also, we are told that they both bought the same number of pieces of fruit. Let's say that each of them bought x fruits.
One apple costs $1 and a jar of honey costs $6. Agnes paid $6 for one honey jar. Also, since Agnes bought x apples, she paid x* $1 for them.
In total, Agnes paid 6+x* 1 dollars for her shopping. We can do similar calculations for Todd. He bought one carton of yogurt for $4 and x peaches for $ 1.25 each.
